Self driving cars work right now. The problem is the cost of failure. If your self driving car works 99% of the time but it kills someone every hundredth trip on average, that's unusable. If your LLM works 99 out of 100 times, that's extremely useful.

Saying “work” is kind of a stretch. Until I see a self driving car navigating through the streets of Bengaluru in the peak traffic periods, I would say it’s still far far away.

All self driving companies have this bias. If it works in US and Europe, it works everywhere. It’s like the same old saying of “it works on my computer. Looks good. Let’s put it on production”. We all know how the story ends ;)

“It’s useless until it works in every single scenario”. Sure that might be fair for self driving cars, but again, doesn’t apply much to LLMs. I don’t care if my chatbot can’t give me accurate answers for medical or physics questions. If it works for the stuff I want, at least most of the time, it’s very useful.
Not Bengaluru but would you take Shanghai for $500? https://youtu.be/PVMCjvsP6O8
Based on the standard of driving in most places I don’t think many drivers can safely navigate that kind of thing either.

Self-driving cars only work on some roads specifically adapted for self-driving cars, and even then they require a team of specialists constantly monitoring them (so it's not very self-driving, the driver just moved to another place).

If they require a specially designed roads, they don't replace cars, they replace trams. And trams are much more efficient, so they don't really replace even them.

You can't put a self-driving car on a random road and expect it to work.

I don’t think that is actually a thing. The places self driving cars are being used right now do not have roads that were especially adapted to support self driving cars.

Not a single routing app that I've tried consistently manages to get you to the correct side of the building when you request a route to a location.

If the problem of figuring out where to drive isn't even solved yet, how can you claim that "self driving cars work right now". They don't, not for any useful definition of the term.

That’s not really a problem with the ‘self driving’ but a lack of data.

Unless they send a human out to every building and mark out which door is the correct one the algorithm is just guessing. I use a “professional” GPS for my job and I don’t trust it at all to get me to the correct entrance, I have to study satellite images and type in the coordinates manually and even then it’ll decide to reroute to the wrong place on occasion because it doesn’t know there’s a gate in the way of its optimal path.

Bit of a hassle, really. If you ever see a big truck stuck on some random road with nowhere to turn around it’s probably the GPS’s fault. One of the first things new drivers need to learn is the GPS will actively try to kill you and can’t be trusted.

I’m not making a direct comparison in terms of the technologies capabilities, but rather the way we perceive(d) them from being just a few years away from taking over.
